Bought to hold a 30M cat5 cable for a behringer mixer. does the job. Plastic is a bit flimsy on the sides - will bend (but not break, so that may be a blessing) and if you thread a cable through the side then it's in your way for winding. That said, it does the job satisfactorily, and for the price, it's absolutely fine. Not suitable for rough use, but just the job for those longer cables, especially if your roadies will insist on coiling your cables like washing line..
